| Summary: | Background: Communication outcomes following stroke are improved when treatments for aphasia are administered early, within the first 3 months after stroke, and provided for more than 2 hours per week. However, uncertainty remains about the optimal type of aphasia therapy. Aims: We compared constraint-induced aphasia therapy (CIAT) with individual, impairment-based intervention, both administered early and daily after acute stroke. Methods & Procedures: This prospective, single-blinded, randomised, controlled trial recruited participants with mild to severe aphasia within 10 days of an acute stroke from acute/subacute Perth metropolitan hospitals (n = 20). Participants were allocated by computer-generated block randomisation method to either the CIAT (n = 12) or individual, impairment-based intervention group (n = 8) delivered at the same intensity (45–60 min, 5 days a week) for 20 sessions over 5 weeks (15–20 hours total). The primary outcome, measured after completing the intervention, was the Aphasia Quotient (AQ) from the Western Aphasia Battery. Secondary outcomes were the AQ at 12 and 26 weeks post stroke, a Discourse Analysis (DA) score and the Stroke and Aphasia Quality of Life Scale (SAQoL), measured at therapy completion, 12 and 26 weeks post stroke. There was a 10% (n = 2) dropout at the primary end point, both participants were in the CIAT group. The estimates for each treatment group were compared using repeated measures ANOVAs. Data from the 26-week follow-up assessment are presented, however, were not included in the between-group comparisons due to the low number of data points in each group.Background: Communication outcomes following stroke are improved when treatments for aphasia are administered early, within the first 3 months after stroke, and provided for more than 2 hours per week.
